How should suspected IP infringement evidence be preserved in China?
Preserve the original source, date, seller identity, product or page, purchase trail and unedited files. Screenshots can help orientation, but a dispute-ready evidence plan may require notarised purchase, platform records or court-preservation measures.
Why it matters
Put the question in the right procedure and timeline
A useful dispute assessment begins with the exact right, current owner, accused act, evidence source and deadline. Enforcement should not start from screenshots alone or from an unverified database entry.
What changes the answer
What can change the answer
Avoid warning the counterparty before volatile evidence is secured. Record who collected each item and how it was stored.
Do not act on the summary alone for a live matter. An official record, service date, document version, party identity or transitional rule can change the conclusion.
What to prepare
Prepare these three points
- 01
Official right numbers and documents showing current ownership and status.
- 02
The latest official record, notice or filing document for this issue.
- 03
A timeline of key events, the earliest known deadline and the result you need.
Next step
Apply the answer to your actual record
Verify the right and the parties before characterising the dispute.
Check whether this fact changes the answer: Avoid warning the counterparty before volatile evidence is secured. Record who collected each item and how it was stored.
Compare administrative, judicial and negotiated routes against the business objective.
